Tremec TKX first cuts

It appears to be identical to the TKO as far as going into an A body. The tunnel may be slightly smaller when done. An automatic floor would be nicer to start with. If no 4 speed tunnel was in place driver side would look like passenger. Or a line down center of tunnel would be cut and spread.
I have this trans bolted to a 400 block using a QuickTime bell housing. SST and American power train also make bell housings that work. Same as TKO.
Made templates of crossmember to be cut. Building my own. Also putting metal back where I cut away material from the torsion bar crossmember.
